| Suggested name | Enrosa |
| Planet type | Hot gas giant |
| Orbiting within Obepa-cali's orbit, Enrosa is an inferior planet and never appears to venture far from NGTS-25; its maximum angular distance from NGTS-25 (elongation) is 70 degrees.
This planet is named after the deity Enrosa, the bringer of prosperity.
An observer on Enrosa would therefore see only one day every four years.
The polar regions are constantly below 162°K (-111°C).
It may have had water vapor oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. The water vapor has probably photodissociated, and the free hydrogen peroxide has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field. Enrosa's surface is a arid desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
Liquid water cannot exist on the surface of Enrosa due to low atmospheric pressure, which is less than 3 percent of Obepa-cali's, except at the lowest elevations for short periods.
Enrosa has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Hawking orbiter. |
